CARTRIDGE PRESSURE CONTROLS INTRODUCTION

APPLICATION

ACB / LCB is a small disc type pressure control for use in refrigeration and air condi-tioning systems. As standard, it is equipped with a 6A contact system having auto-matic or manual reset.

The control is robust and reliable in operation in many types of units.

The small size, lightness and high degree of protection means that it can be mounted directly on the refrigeration systems where pressure regulation is required.

The control is available with different pressure settings and pressure connections to suit customer requirements.

All these features reduce installation costs and save space.

ACB / LCB cartridge controls are used in refrigeration and air conditioning systems with CFC, HCFC, HFC as high and low pressure safety cut in and cut out as well as fan cycling.

FUNCTION ACB / LCB contains one or more stainless steel discs. Each disc reverses its curvature when pressurized to a customer specifi ed value.

When the disc „snaps”, electrical contacts open (or close) by means of a push shaft. The pressure control resets automatically when pressure drops below (or rises above) a preset value.

PRINCIPLES OF OPERATION

PRINCIPLES OF OPERATION

As pressure is applied through the connection on to the diaphragm, the diaphragm is pushed up against the operation shaft.

When the operation shaft rises, it pushes up the contact plate, so that H contact and C contact become disconnected (in Normally Closed switches) or H contact and L contact become connected (in Normally Open switches).

As the pressure in the connection decreases, the diaphragm returns to its original state, and the operation shaft lowers, causing the contact plate to return to its original position.
